GMT). This is the sixth in our series of weekly webinars for developers about EPA's data. Each week we're highlighting different datasets we hope you'll use
to design an app for EPA's Apps for the Environment challenge. This webinar will cover data systems that are related to Superfund sites, hazardous waste management
facilities, and brownfields. Superfund deals with hazardous waste sites and brownfields deal with redeveloping properties that are or could be contaminated.
All of these systems include locational information. They can be used in conjunction with EPA's Facility Registry System (FRS) ( ...

. > Upcoming Live Internet Seminars Curso de Capacitación sobre Remediación de Sitios Contaminados - August 1 and 2, 2011. Una buena caracterización de los sitios contaminados es esencial
antes de embarcarse en proyectos de restauración. Para tal fin, es necesario obtener datos de calidad y características acordes a las necesidades del proyecto
y que conformen con normativas medioambientales en vigor. En este seminario de dos días se tratarán los procedimientos administrativos para la caracterización
de sitios, los procesos de supervisión y verificación del cumplimiento normativo, y los plazos de respuesta de la autoridad. Metas del seminario: (1) describir
los tipos de análisis químicos y físicos para la caracterización de sitios contaminados (métodos, equipos, y limitaciones); (2) interpretar los resultados
de los principales tipos de análisis utilizados en la caracterización de sitios contaminados; (3) describir la preparación y el contenido de un estudio de
caracterización de pasivos ambientales; y (4) proporcionar estudios de casos reales sobre evaluación de los riesgos ambientales y de salud. Para obtener

on providing participants with an overview and basic understanding of the U.S. Constitution and those laws that have a direct effect on the OSC. Participants
will gain information on such topics as takings, due process, liability, and just compensation. For more information and to register, see
. Greener Cleanups - EPA's Methodology for Understanding and Reducing a Project's Environmental Footprint - August 10, 2011, 1:00PM-3:00PM EDT (17:00 19:00
GMT). The process of cleaning up a hazardous waste site uses energy, water, and other natural or materials resources and consequently creates an environmental
footprint of its own. The US EPA is developing a methodology for evaluating the environmental footprint in order to reduce the footprint and improve the outcome
of cleanup under any regulatory program. EPA will host an interactive Internet seminar to provide information about the environmental footprint assessment
methodology and to obtain feedback from the environmental remediation community. This two-hour seminar will: (1) discuss the metrics for environmental
footprint assessment and the methodology for estimating or quantifying the footprint; and (2) provide an interactive case study to allow participants to
get a feel for the process of calculating an environmental footprint and evaluating options to reduce it. An open forum will be held after the presentations,
during which participants will be able to submit questions and feedback to the speakers. For more information and to register, see
. ITRC Use and Measurement of Mass Flux and Mass Discharge - August 16, 2011, 2:00PM-4:15PM EDT (18:00-20:15 GMT). The ITRC technology overview, Use and Measurement
of Mass Flux and Mass Discharge (MASSFLUX-1, 2010), and associated Internet-based training provide a description of the underlying concepts, potential
applications, description of methods for measuring and calculating, and case studies of the uses of mass flux and mass discharge. This Technology Overview,
and associated Internet-based training are intended to foster the appropriate understanding and application of mass flux and mass discharge estimates,
and provide examples of use and analysis. The document and training assumes the participant has a general understanding of hydrogeology, the movement of chemicals
in porous media, remediation technologies, and the overall remedial process. For more information and to register, see or
. OSC Readiness Presents...Debris Management Issues during Natural Disasters - August 23, 2011, 1:00PM-3:00PM EDT (17:00-19:00 GMT). The Debris Management
Issues during Natural Disasters session will discuss debris-related roles of Emergency Support Function-3 (ESF-3) and ESF-10: the division of responsibilities
and coordination between the two ESFs during natural disaster and contaminated debris responses. For more information and to register, see
. ITRC Permeable Reactive Barrier: Technology Update - August 25, 2011, 11:00AM-1:15PM EDT (15:00-17:15 GMT). The ITRC Technical/Regulatory Guidance
Permeable Reactive Barrier: Technology Update (PRB-5, 2011) and associated Internet-based training is intended to help guide state and federal regulators,
consultants, project managers, and other stakeholders and technology implementers through the decision process when a Permeable Reactive Barrier (PRB)
is being considered as a remedy, or part of a remedy, to address contaminated groundwater; and to provide updated information regarding several technical
aspects of the PRB using information attained from the more than 15 years that the PRB has been a viable and accepted in situ remediation technology for contaminated
groundwater. The guidance and training provides an update on PRBs to include discussions of additional types of reactive media and contaminants that can be
treated, design considerations, construction/installation approaches and technologies, performance assessment, and longevity. For more information
